Wright a multiplication problem in witch the product is between 0.05 and 0.75

The half of the mixed fraction -2 3/8 as a fraction is -19/16.

A mixed fraction is a combination of a whole number and a proper fraction. It represents a quantity that is greater than one, with a fractional part that is less than the whole. For example, 2 3/4 is a mixed fraction, where 2 is the whole number and 3/4 is the proper fraction part. It is commonly used to express measurements, such as in cooking or in everyday life situations.

To find half of a mixed number like -2 3/8, we need to convert it to an improper fraction first.

The mixed number -2 3/8 can be written as an improper fraction as follows:

-2 3/8 = -((2 * 8) + 3)/8 = -19/8

Now, to find half of -19/8, we divide it by 2:

(-19/8) ÷ 2 = -19/16

Therefore, half of -2 3/8 as a fraction is -19/16.

Answer:

A

Step-by-step explanation:

It takes 10 workers 5 days to complete a road repair when working 2 hours a day.

So, this becomes : man hours required to finish the work.

Given is, if 2 people work for 5 hours a day, then let the number of days to finish the road be = d

So, total man hours =

Now, or

Hence, it will take 10 days for 2 people working 5 hours daily, to complete the work.

It will take 10 days for 2 people working 5 hours a day to finish the road repair.

Further Explanation:

From the question;

10 workers can finish road repair in 5 days working 2 hours a day

We need to find;

The number of days required to complete the road repair by 2 workers  working 5 hours a day.

Assuming the number of days required to complete the work is x

Number of working hours of 10 people is 10 hours ( 2 hours a day for 5 days)

Number of working hours of 2 people is 5x hours (5 hours a day for x days)

Note that; the number of workers or people is inversely related to the number of working hours.

Therefore;

Product of number of people and working hours or work done is a constant

Thus;

10 × 10 =  2 × 5x

100 = 10 x

x = 10

Therefore;

2 workers working 5 hours a day will require 10 days to complete the road repair.

Answer:

Step-by-step explanation:

Final answer:

The solution set of the equation 4x² - 25 = 0 is {±2.5}.

Explanation:

The given equation is a quadratic equation of the form ax² + bx + c = 0, where a = 4, b = 0, and c = -25. To find the solution set, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

Plugging in the values, we have:

x = (-0 ± √(0² - 4(4)(-25))) / (2(4))

Simplifying further, we have:

x = (±√(0 + 400)) / 8

x = ±√(400) / 8

x = ±20 / 8

Hence, the solution set of the equation is {±2.5}.

What is division?

Division is a process of splitting a number into two or more equal parts.

Given is that Jan has 500 pieces of paper she prints as many copies as possible of a 16 page report.

We can write that the number of pieces of paper left as the remainder of the division of 500 and 16. We can write that -

{p} = 500/16

{p} = 16 x 31 + 4

{p} = 4

Therefore, the pieces of paper left would be 4.
